Hi Ray, Your patch works on my ROG Flow X13 (Cezanne, DCN 2.1). I applied it to 7.3 in place of mine and booted with amdgpu.dcfeaturemask=0xa. debugfs shows PSR support on eDP-1 from both the sink and the driver, and with the screen still, psr_state goes to 6 (PSR_STATE3) about a second after the last update and stays there Tested-by: Hugo Sales Thanks, Hugo
